Definitions

  • TITLE "Automatic lifting hook” to Dellai Graziano.
  • the present finding concerns a lifting hook with a safety device, which is capable of automatically picking up and releasing a load, according to the general part of claim 1.
  • Article 172 of DPR 547/77 requires that "hooks for lifting apparatuses must be provided with devices for closing their opening portion or be shaped so as to prevent ropes, chains and other holding members from become detached",
  • a closing safety device which is made up of a strap that is hinged onto the body of the hook, said strap, being provided with a swinging movement, taking care of keeping the aforementioned opening portion open, during the hooking phase of a metal cable, a fibre cable, a chain, a bucket or another apparatus, or closed, when lifting the load.
  • the strap In its most simple configuration, the strap is normally arranged with the opening portion closed, said portion being held through an elastic clip system or, more simply, it is kept against the body of the hook only by effect of the weight of the strap itself.
  • the drawback of such an arrangement consists of the fact that the movement/rotation of the strap to free the opening portion occurs manually, by pushing the strap so as to overcome the contrast force of the antagonist spring, or by acting on a small pin projecting from the aforementioned strap.
  • the main purpose of the present finding is to make a lifting hook that is equipped with a safety device, of the type made up of a swivel strap, which is without the drawbacks seen in similar products of the known type. This is obtained, according to the finding, by configuring the automatic lifting hook according to the characteristics present in the main claim 1.
  • tab. I shows a first embodiment of the hook according to the finding, in resting conditions, with the opening portion open;
  • - fig. 2 shows the hook according to fig. I, in operative conditions, with the opening portion closed;
  • tab. HI shows a second embodiment of the hook according to the finding, in resting conditions, with the opening portion open;
  • - fig. 4 (tab.IV) represents the hook according to fig.3, in operative conditions, with the opening portion closed;
  • tab.V shows a third embodiment of the hook according to the finding, in resting conditions, with the opening portion open;
  • the lifting hook according to the finding is made up of a hook-shaped body 1 , which is provided with the strap 2, which is hinged on the pin 3 and can perform a swinging movement, that closes the opening portion 4 and of the connection eyelet 5, all in a per se known manner.
  • the body 1 and the eyelet 5 constitute two separate elements and are reciprocally held through the shaft 6, which is coaxial with respect to said two elements, said shaft having its upper threaded portion that is arranged on the eyelet 5 and held through the locking nut 7, whereas the remaining portion is inserted and slides inside the sleeve 8, which is obtained in the upper part of the body 1 and is closed by the flange 9.
  • the shaft 6, in an intermediate position, is provided with a collar 10, which has the function, in combination with the upper flange 9, of defining a chamber 1 1 where a preloaded spring 12 and a spacer bush 13 are coaxially inserted.
  • the shaft 6 ends below with a tang 14, where a mechanical rotary-translation transmission of the pinion/rack type is obtained, wholly indicated with reference numeral 20, for automatically closing/opening the opening portion 4, which consists of a toothed portion 21 that is obtained on the aforementioned tang, which engages with a corresponding toothed sector 22 obtained on the strap 3 and centred on the pin 3.
  • the shaft 6 ends, at the bottom, with a tang 14, where a lever type mechanical rotary-translation transmission is obtained, wholly indicated with reference numeral 30, for automatically closing/opening the opening portion 4, which consists of a lever 31 , which is hinged to the two ends, respectively, on the tang 14, through the coaxial pin 32 and on the strap 2, through the pin 33 that is arranged in an eccentric manner with respect to the rotation pin 3 of said strap.
  • the shaft 6 ends, at the bottom, with a tang 14, where a mechanical rotary- translation transmission of the snap-fitting type is obtained, wholly indicated with reference numeral 40, for automatically closing/opening the opening portion 4, which consists of a knob 41, which radially projects from the aforementioned tang 14, which engages in a seat 42 that is radially obtained on the head of the strap 2,
  • the reciprocal shaft/hook movement causes the mechanical transmission 20/30/40 to move, bringing the strap 2 back to the closed position of the opening portion 4 and holds it in such a position for all the time that the weight "P" acts.

Abstract

La présente invention concerne un crochet de levage automatique, du type constitué d'un corps (1) en forme de crochet, doté d'une sangle (2), articulé sur une broche (3) et apte à réaliser un mouvement de basculement qui ferme la partie (4) ouverture du crochet et d'une partie (5) de raccordement supérieure composée d'un œillet, d'une fourche, d'une plaque ou d'un autre dispositif adapté à ce but. Ce crochet (100) est notamment caractérisé en ce que le corps (1) en forme de crochet et la partie supérieure de la partie (5) de raccordement forment deux éléments séparés, maintenus réciproquement à travers un axe (6) intermédiaire, agencé de manière coaxiale par rapport aux deux éléments (1, 5) susmentionnés, l'axe se déplaçant axialement, déplace la sangle (2) afin de fermer la partie (4) ouverture.
